PADLOCK.

Application med April 4,

The objects of the invention are to provide a keyless padlock in which the protrudingshackle or link is locked from movement,

by means of. a sliding latch which engages with one arm of the shackle and which can only be released by the'interpositi'on of a rolling ball between movable parts, the'function of which is to complete the connection of the parts in such a-manner that by. means of a slight movement of the other arm of the shackle, the sliding. latch. can be released from engagement with the arm ,of the shackle arm to permit this arm to be with.- CllitWIrflOllttllB case.

when the ball is interposed and. the rock armis depressed thelatch bar will be released from the shackle. v

Also a labyrinth passage is provided within the casing which must be .traversed by the ball before it can enter between the pivoted arm of the shackle and the rock arm to make the armloperative. -This passage differs in shape in different locks and its structure and ramifications mustbe familiar to the owner of the look before the ball can be positioned in operative position between the pivoted armofthe shackle and the rock arm, hence making it impossible for one unacquainted with its construction to open the lock.

The invention" ishereina'fter described,

and specifically pointed outin the claims.

In the accompanying drawings, Figure 1 is a plan-of the lock with the coverremoved showing the device in the locked position. Figure 2 is a transverse section of cover and easing. Figure 3 is a plan showing the device unlocked and the sliding latch bar released by the interposition of a ball between the pivoted end of the shackle and the rock arm. Figure 4 is a perspective of the sliding latch. Fig. 5 is a plan of a modified form of lock. In these figures A represents the casing of the lock, B represents the loop of the shackle, one arm C of the shackle .be-' ing pivoted upon a pin D in the casingand' yieldingly depressible by means of the'slotted The invention comprises, a casing in which illustrated in the accompanyingdrawings 1927. SerialNo.i 180;957.. h

journal opening E in which the pinprojects and a coiled spring F therein. -The other arm G of .the shackle is provided with shoulder H normally engaged with a latch bar I shd'ingly movable between a rectilinear guide shoulder J and guide pins or, lugs J I and isoperated to release the shackle by means ofsa rockarm K pivoted at L in the casing and engaged at M with the latch bar.

The'pivot'ed endfC of. the hasp and the ad-.

jacent'edge Oof the rock arm are separated a normally, by an inclined channel P but when a ball is caused to roll between these opposed surfaces a downward pressure uponthe pivoted side of the shackle will cause the ball to press against the side of the rock arm,

and the latclrbarwill be withdrawn from the shoulder thus releasing the shackle. To

make thepositioningof the ball in the chan-V nel .difiicult to obtain so that only one fa miliar withthe structure of the lock can, Y

operate it, alabyrinth is formed of walls of irregular shape, at R, S, and T so positioned that channels U, V, V, and 'X are formed between them which the ball must follow 1 correctly beforeit can enter the channel P, which is accomplished by first tilting'theball to the left until it isstopped-by the notch X in the'wall of the casing and stopped from entering a pocket Z in the labyrinth. Then the casing is tiltedto the right until the 7 ball passes into the channel P.

.I do not, however, confine the shape of: the v r walls or channels to any one design but any tortuous channel suitable to form a confusing labyrinth is within the scope ofthe invention and following claims.

A cover A is pressed into a dovetail shoul- I der A" in the edge of the casing A.

In Figs-a similar device is shown, withthe exception that thehasp B is not pivoted but moves longitudinally in the casing andwhen released is thrown outward by means of a spring B. p

Also a pivoted detent B locks the rock arm K when the has'p is pushed in to operate the rock arm and latch bar K.

This construction is useful since thelatch bar will remain withdrawn'until the arm B on the detent is struck by a shoulder B- on the shackle. Y i

Having described the invention what I claim as new and desire to secure by Letters Patent is:

1. In a keyless padlock, in combination, a

casing, a shackle loop having one armpivoted be traversed by saidball before it can enter and longitudinally depressible in the wall of said casing, the other arm being provided with a retaining shoulder adjacent to its extremity, a latch member movable in said casing and engageable with said shoulder to retain the same, a movable operating member for said. latch member, and a ball interposable between said pivoted arm ofsaid shackle and said latch operating member.

2. In a keylesspadlock, in combination, a casing, a shackle loop having one arm PIVOtQCl and longitudinally depressible in the wall of said casing, the "other arm being provided with a retaining shoulder adjacent to itsextremity, a latch member movable in said casing and engageable with said shoulder to retain the same, a movable operating member for said latch member, anda ball interposable between said pivoted arm of said shackle and said latch operating member and a labyrinthine passage or channel, in said cas ing leading to a position between said pivoted shackle arm and said latch operating member.

In a keyless padlock, a casing, a siiackle loop having a spring pressed arm pivoted and depressible in said casing, the other arm being provided with a locking shoulder, a latch bar loop having a spring pressed arm pivoted and depressible in said casing, the other arm being provided with a locking shoulder, a latch bar slidable in said easing into and out of engagement with said shoulder, a rocking member for operating said latch bar, there being a channel separating said rocking member from Q and said operating member, will cause said the inner extremity of said pivoted shackle arm, a ball in said casing movable into said channel to cause an inward movement of said arm to operate said rocking member and release said latch and labyrinthine walls in said casing forming circuitous channels that must channel to cause an inward movement of said arm' to operate said rocking member and release said latch and labyrinthine walls in said casing forming circuitous channels that must be traversed by said ball before it'can enter said channel between said arm and rocking member, and a second rock arm for locking said rock arm when said latch bar has been withdrawn and a spring for releasing said shackle, said locking means being withdrawn from said rock arm by the return movement of said shackle.

6. In a keyless padlock, a casing, a shackle, having a latching shoulder at one end and having one arm longer than the other and longitudinally movablein said look, a transversely movable latch engageable w th said shoulder and an operating member therefor spaced from the longer end of said shackle and a ball loose in said casing which when 1nterposed between said longer end of said shackle and said operating member, will cause said member to release said latch on the inward movement of said shackle.

7. In a keyless padlock, a casing, a shackle, having a latching shoulder at one end and having one arm longer than the other and longitudinally movable in said lock, a transversel movable latch engageable with said shouldbr and an operating member therefor spaced from the longer end of said shackle and a ball loose in said casing which when interposed between said longer end of said shackle member to release said latch on the inward movement of said shackle and a return spring for said. shackle. a r

In testimony whereof I aflix my signature.
